I received MeasuPro Wireless Bicycle Computer in return for my honest review. MeasuPro Wireless Bicycle Computer is not only a bike speedometer, it's also a heart rate monitor, timer, odometer, and calorie tracker. My son loves to bike and has always kept up with his distance by memory. He had no way to track the things included with this bicycle computer. This allows him to enjoy bike riding while having the capability to track all the things that a stationary bike would track. It's very easy to install. Instructions were simple and easy to follow. This computer is not bulky. My son can control the handle bars while keeping track on this computer. It's easy to use and can be removed when not in use. Since installing, my son has been able to track his progress He can actually set goals since he's able to keep up with his rides. It's nice that this computer is waterproof so he doesn't have to worry about getting caught in the rain. Overall, this is a very nice bicycle computer. Highly recommend for any bike rider!
